It's only the EU bit these kind of law tend to impact products all around the world.
Maintaining different products for different markets is difficult and expensive. Making the battery replaceable is not very hard to do so it's easier to produce one kind of product with replaceable battery for the whole world rather than maintaining two different production lines.
Maybe. I know it's a different scale but in the EU there's a standard connector for all electric cars (CCS Type 2 Combo) and that's become the defacto standard for most cars in most countries, but Tesla maintains their own connector in non-EU territories. I wouldn't put it past Apple is all I'm saying: controlling the charge port is very important to companies that profit from tight vertical integration.
To be fair a three-phase connector doesn't make sense in the US with their bonkers electrical system where you get either 110V to neutral or -110V to +110V.
Separate DC charging standards make no sense at all, though. From what Technology Connections says Tesla at least switched the signalling to be compatible, so all you need is a physical adapter. Maybe they figured that they don't want to fight all the other manufacturers, or make additional money from non-Tesla drivers using their network, or something.
True, but we don't know how many strings are attached to that. The Tesla connector is going to be made 'open source', but that doesn't mean anything in terms of it being free to use or permissable. I hope it's being done in good faith but The Dipshit has something of a record to the contrary...
